Hi Max,

One particular unusual environment I have observed is such that on a NFS client, files are reported as having owner/group being nobody/nobody, but actual access to files is correctly handled by the NFS server using UIDs/GIDs. Correctly meaning that the effective UID/GID of the process executing on NFS client is handled by the NFS server when granting particular operations on files/directories as they appear on NFS server. These are the mount options reported on NFS client, which is Linux (CentOS 6.5):

server:/directory on /directory_nfs type nfs (rw,vers=4,addr=192.168.xxx.xxx,clientaddr=192.168.xxx.xxx)

The NFS server is a Solaris box (Solaris 10, sparc) which speaks NFSv4 and runs the nfsmapid daemon, but the client is not running the idmapd.


Hope this helps.

Regards, Peter
